Started a new job a few weeks ago and now that the new team is all done with training, we’re going through and trying to fix things we’re coming across.  One of the errors that showed up on every single domain controller is 8194 and has to do with Group Policy Registry happening every 5 minutes .  The fix for this is pretty simple.  Look up the ID of the GPO in the event log.  Navigate to c:\programdata\microsoft\group policy\history.  You may have to show hidden folder or system folders if they are not visible.  If you drill into the problem directory, you should come across a Registry.xml file that is 0Kb.  Rename the ID folder to <original name>_old.  The errors should stop.

It seems that for whatever reason or another, that policy gets corrupted and needs to be recreated.
